. I To all whom it may concern:

Be'it known that I, HERBERT A. IRELAND, of Norwich, in the county of Chenango, in the State of New York, have invented new and useful Improvements in Carburetors, of which thefollowing, taken in connection with the'accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in carbure ters involving in addition to thefeed for the gasolene or other liquid hydro carbon and air, a floatcontrolled water-feed which together with the air and gasolene or other liquid hydro-carbon is adapted to be'drawn into and thoroughly mixed in the carbureter and delivered as an explosive mixture to the engine.

Briefly described, the apparatus by which I carry outthe objects of my invention comprises a casing having a, mixing chamber therein, and a combined tvater and hydrocarbon feeder connected to the casing and divided into compartments having inde pendent discharges into the mixing chamber, together. wlth. floats in the compartments carrying valves which cooperate with valve seats provided therefor on feed nozzles projecting into the compartments and.

carried by the cover of such compartments.

In the drawingsFigure 1 is alongitudinal vertical sectional view of a carbureter embodying the various features of my inventio'n showing particularly the water chamber and'float valve therein and the needle-valve for regulating the amount of water admitted to the mixing chamber. Fig. 2 is a horizontal sectional view of the same carburetor taken on line 2-2 Fig. 1. Fig. 3 is a transverse vertical sectional view through the same carbureter taltenon line 3-3, Fig. 1'.- 1 I As shown in the drawing, 'th apparatus consists of-a cup-shape shell divided by a centre] vertical partition"2 into opposite similar compartments 3.' and L both of which are covered b a single cap 5 forming the top of the s ell -1 and. adapted to be secured thereto by suitable fastening means as bolts -6-. The chambers -3- and --4:. constitute reservoirs for receiving and retainin limited A quantitiesof gasolene .or other liqu1d hydrocarbon and water respectively and are provided with separate inlet or supply plpes 7 and -8 and separate outlet pipes or passages and --10 both of which Specification of Letters Patent.

latter discharge upwardly into a common mixing chamber '11- having an air inlet -l2 and an outlet 13' adapted to be connected in any Well known manner to the firing chamber or chambers of the engine not shown. The inlet conduits7- and -8---- are preferably secured to and extend downwardly from the central portion oi. the cap 5 and terminate at their lower ends in the upper portions of their respective chambers 3 and 4- and are formed with constricted outlets forming valve seats 14- and 15. Movable vertically within the chambers are similar floats -16 and l7 having upstanding valves l8 and 19- coacting with their respective valve seats 14'- and 15- for separately controlling the passage of .gasolene and water into their, respective chambers 3'and' 4-. In like-man ner the outlets -9 and 10 which discharge, into the mixingchamber -11 are provided respectively with valve seats 19 and 20 coactingfiwith separate needle valves -21- and -22:- which are engaged in threaded apertures in the upper side of the mixing chamber andare vided withexternal hand ieces 23 by which they may be adjuste at will to con trol the quantity of gasolene or water admitted to the mixing chamber.

It is now clear that when predetermined quantities of gasolene and water have been admitted to their respective chambers --3- and t, the corresponding floats -16- and 17 will be operated to cause the valves 18-- and 19- to close against their seats 14- and -15 andlthereby cut off further supplies until they fall'below predetermined levels, the floats 1 6- and -1 7 and the respective valves -18- and 13 serving to automatically regulate the supply of gasolene and water to their respective chambers 3- and -4-. The valves 2l and 22 in the outlets 9 and 10 are adjusted at will and also serve to control the amount of gasolen'e and water from the chambers 3 and -4- to the mixing chamber 11-. I

The shell -1-- is provided with suitable shoulders 25- adapted to be engaged by the floats -16 and 17 to limit their downwar g movement, thereby limiting the amount 0 I opening of the valves l8 and 19-.

The supply of the explosive mixture to prothe engine may be regulated by means of a throttle valve 28 which is located as usual between the mixing chamber and outlet of the carbureter and may be operated at Will by any suitable mechanism not necessary to herein illustrate or describe.

It is now clear that the gasolene or other liquid fuel together With the air are drawn simultaneously into the mixing chamber by the exhaust produced by the piston of the engine, the fuel and Water being introduced into said mixing chamber through separate jets and regulated by separate needle valves, and that the throttle is located between the points of entrance of the fuel and Water and the outlet of the carbureter leading to the engine, thus enabling the operator to control the mixture to a nicety according to the requirements of the enginelunder varying loads. In other Words the separate fuel and water jets discharge into a Water chamber between the air inlet and throttle valve so that the infiowing jets of fuel and Water are intercepted by the inflowing current of air in the mixing chamber Where the component parts of the mixture are thoroughly agitated and mixed before pasing outwardly through the throttle valve to the engine.

What I claim is:

In carbureters, the combination with a casing having a mixing chamber therein, of a combined Water'and hydro-carbon feeder comprising a cup-shaped shell connected to one side of said casing, a vertical partition dividing the shell into independent compartments, outlet conduits for said co-m'partments leading into and discharging upwardly Within the mixing chamber, a cover for said shell, feed nozzles projectinginto the shell through said cover and having valve seats at their discharge ends, floats in said compartments, and upstanding valves carried by said floats to engage the valve seats of said inlet nozzles.

In Witness whereof I have hereunto set my hand on this 1st day of May, 1911.
